Page 3: Quick Start Installation
INSTALLATION The A.C. power should be wired into the GD-1000 (TB5) by a qualified electrician. This is not covered by Eagle Microsystems, Inc. or its distributors. The GD-1000 gas sensor can be separated from the GD-1000 meter 1000ft or more if the appropriate cable is used. - Page 4 MAIN SCREEN After the sign-on screens show the company name, firmware version, check-sum, and the time and date, the stabilize delay timer is displayed (see left display above). Alarms associated with the gas sensors are inhibited, which are loss of signal and set point alarms (danger and critical). One can exit this screen by pressing ESC. The stabilization delay timer will continue counting down, which is indicated on the main screen display.
- Page 5 (MNU) SETUP MENU This screen allows one access to the calibration, configuration, and alarm set point screens. All selections require one to enter a password before access is allowed. CAL: Access the sensor inputs and analog output calibration menu CFG: Access the configuration parameters (full-scale, relay assignments, etc.) ALM: Access the danger and critical alarm set points for each channel.
- Page 6 CONFIGURATION From the SETUP MENU screen, press CFG to access the configuration parameters. The default password is 0000, and the push buttons operate as follows: ADJ: Make adjustments to the parameter value. ENT: Accept the change to the parameter. ESC: Normally returns to the previous screen. When adjusting a parameter, the adjustment to the parameter value is discarded and the original value is restored.
- Page 7 CONFIGURATION (continued) Parameter: CH2 CRT RLY This parameter sets the relay output for the channel two, critical level set point. Choices are K1, K2, K3, K4, K5, K6, and OFF. The relay can be shared with any other alarm. The default relay is K3. The internal buzzer and external horn (if enabled) are activated by the following events: Channel 1 &...
- Page 8 CONFIGURATION (continued) Parameter: A-DIAL DL This parameter sets the auto-dialer activation delay to avoid false alarms. This delay is added to the set point delay (SP DLY) time. The range is from zero (0) to 3600 seconds. The default is ten seconds (10s). Parameter: BATTERY OPT This parameter controls the optional battery backup options.
- Page 9 4-20mA ANALOG INPUT (GAS SENSOR INPUT) CALIBRATION USING A GAS IMPORTANT: The gas sensor should be calibrated to the meter using the gas calibration procedure on this page. The gas sensor calibration allows one to calibrate the gas sensor input using air (zero ppm or mg/L) and a calibration gas, which is within the gas sensor range.
- Page 10 GAS INPUT CALIBRATION WITH A 4-20mA CALIBRATOR IMPORTANT: The gas sensor should be calibrated to the meter using the gas calibration procedure on the previous page. The user can calibrate or check the (milliampere) mA signal input. Enter the mA calibration mode from the main operating display by pressing any push button, MNU, CAL, enter password (default 0000), SNS, mA, and then select CH1 or CH2.
- Page 11 CHANNEL TWO 4-20mA OUTPUT An optional PS-1000(S)-AOUT daughter board is used to furnish the second analog output. POWER UP FUNCTIONS Press and hold the push button(s) while applying power to the GD-1000. DESCRIPTION I/O test Factory default...
- Page 12 EVENT LOG AND TIME & DATE An event log function is available that allows one to view certain events (danger and critical alarm) that occurred. Up to 250 events are stored. To view the log, from the main operating screen, press any push button and then LOG. LOG MENU SELECTIONS VIEW Access the event log selection menu.

WIRING (continued) 4-20mA POWERED (ACTIVE) CALIBRATOR WIRING The relay function list below is the default, but one can reassign the relay outputs to suit the requirements of the installation. K4 & K5 (TB4) are optional relays and are not typically installed. The relay contacts are “dry”... -

GAS SENSOR INTERNAL WIRING (REF. ONLY) BASIC SYSTEM TROUBLESHOOTING Check that 115 VAC (230VAC if used) is reaching TB5. • Check that the ribbon cable to the display is plugged in at both ends and fully seated. • Instrument does not Make sure power is disconnected and then remove fuse and check for continuity. - Page 17 AC power interruption. The user can power-down the GD-1000 if it’s operating on the battery backup when the user depresses the left- most push button in the main operating screen (where the gas detector level(s) are/is displayed) for fifteen seconds until the LCD display goes blank (this is not the same as the short-term battery option above).
